How does my ratings distribution compare?

This is how scores are distributed in the population.-->

I have rated 110 movies--a few more than the median. My mode is 3 whereas the population mode is 4.

Thinking about my own data is not just narcissism; I have found it useful when looking at supermarket loyalty card data, telephone call data, and drug prescription data. I find it gets me thinking in more interesting ways.

For instance, I never give any movies a 1, so how come other people do? Couldn't they have guessed they wouldn't like that movie before seeing it? Personally, I never watch a movie unless I expect to like it at least a little. Ah, but that wasn't always the case! When my kids were young and living at home, I often suffered through movies that were not to my liking. Come to think of it, it is not only parents who sometimes watch things picked by other people. Room mates, spouses, and dates can all have terrible taste!
